Infineon IHW30N110R3: A High-Performance 1100V Reverse Conducting IGBT for Robust Power Conversion
The relentless pursuit of higher efficiency, power density, and reliability in power electronic systems drives continuous innovation in semiconductor technology. At the forefront of this evolution is the Insulated Gate Bipolar Transistor (IGBT), a workhorse for high-voltage and high-current applications. The Infineon IHW30N110R3 represents a significant leap forward, embodying the advanced Reverse Conducting IGBT (RC-IGBT) technology tailored for robust and compact power conversion solutions.
This device is engineered to handle demanding environments, offering a blocking voltage of 1100V and a continuous collector current of 42A at 80°C. Its primary differentiator is its reverse conducting capability. Unlike a standard IGBT which requires an anti-parallel diode for reverse current flow, the RC-IGBT monolithically integrates this function into a single silicon chip. This ingenious design eliminates the need for a separate diode, leading to a drastic reduction in the overall package size and module footprint. The result is a marked increase in power density, allowing designers to create smaller, lighter, and more cost-effective systems without compromising performance.
The IHW30N110R3 is particularly optimized for soft-switching topologies, which are prevalent in modern high-frequency power supplies. In applications such as industrial SMPS (Switch Mode Power Supplies), uninterruptible power supplies (UPS), and renewable energy inverters, switching losses are a critical factor for overall efficiency. This device excels here, featuring low saturation voltages (Vce(sat)) combined with ultra-low turn-off losses (Eoff). This optimal trade-off ensures that energy dissipation is minimized during operation, leading to cooler running temperatures and higher system efficiency.
Robustness is a cornerstone of the IHW30N110R3's design. It boasts a short-circuit withstand time (tsc) of 5µs, providing a critical safety margin for control circuits to react and protect the system under fault conditions. Furthermore, its positive temperature coefficient of Vce(sat) facilitates easier paralleling of multiple devices for higher power output, as it promotes an even distribution of current across the chips. The TO-247plus housing (3-pin) package ensures superior thermal performance, enabling effective heat dissipation away from the silicon die, which is crucial for maintaining long-term reliability.
